Create a Kubernetes Job template for Team Aurora that runs a busybox command across multiple completions in parallel, with specific pod labels and container configuration.
Create a Pod that uses a postStart lifecycle hook to write a custom message to the nginx welcome page, expose it via a NodePort Service, and verify the hook ran successfully.
A Deployment is using a disk-backed emptyDir volume. Convert it to a memory-backed tmpfs volume for better performance — but make sure to set a size limit to prevent the Pod from exhausting the node's RAM.
A Pod is running nginx and exposed via NodePort. Copy a local HTML file into the running Pod so NGINX serves it as the default homepage using only imperative commands.
